Katy (probably the best in the area), Sugarland, Stafford, all pretty good areas with great school districts. Richmond and Rosenberg have some really nice areas (like Greatwood), but the school districts aren't the best, and there are a lot of run down neighborhoods.
Fulshear seems to be kind of in the country from what I know, so if you prefer a country atmosphere, check it out. Katy / Cinco Ranch look likes it's probably closer to Sealy.
Fort Bend ISD has been ranked higher than Lamar Consolidated (which would be the Richmond/rosenberg schools). Here's a good place to look for community info.
